Materials Data on HoTlTe2 by Materials Project
HoTlTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ho3+ is bonded to six equivalent Te2- atoms to form HoTe6 octahedra that share corners with six equivalent TlTe6 octahedra, edges with six equivalent HoTe6 octahedra, and edges with six equivalent TlTe6 octahedra. The corner-sharing octahedral tilt angles are 9°. All Ho–Te bond lengths are 3.09 Å. Tl1+ is bonded to six equivalent Te2- atoms to form TlTe6 octahedra that share corners with six equivalent HoTe6 octahedra, edges with six equivalent HoTe6 octahedra, and edges with six equivalent TlTe6 octahedra. The corner-sharing octahedral tilt angles are 9°. All Tl–Te bond lengths are 3.49 Å. Te2- is bonded to three equivalent Ho3+ and three equivalent Tl1+ atoms to form a mixture of corner and edge-sharing TeHo3Tl3 octahedra. The corner-sharing octahedral tilt angles are 0°.
